Application led September 22, 1925. `Serial No. `5778'3.

providing astructure constructed so as to be readily attached to an existing timepiece with detachable designators mounted thereon adapted to be positioned adjacent the minute graduations of the timepiece so as to designate the times at which the events occur.

A still further object resides in providing an annular back having a central opening, whichback is arranged to beattached to the timepiece so that the hands and face thereof are visible through the opening in said back and to position the detachable designators along the innerperipherv of said back so that the same may be placed adJacent the minute graduations of the timepiece.`

Another object resides in providing .an

annular supporting member in conjunctlonv with said back for carrying additional designators to indicate the occurrence of other events.

. A feature of the invention resides in providing supporting membersupon the back for holding display cards or other means having data associated with the useV `,of the invention or advertisingv matter inscribed thereon. Y y

Other features of the invention reside in the detailed construction 4thereof as disclosed in the following drawings, description and claims.v Y

In the drawings illustrating my invention in one form: f

Fig. 1 is a front elevational view `of my invention illustrating the same attached to a timepiece.

Fig. 2 is a rear view of the invention removed from Vthe timepiece.

Fig. 3 is a fragmentary sectional view taken on line 3-3 of Fig. 2.

Fig. 4 is an enlarged fragmentary sectional view taken on line 4-4 of Fig. 1. y

Fig. 5 is a perspective view of one of the designator bodies.`

Fig. 6 is a perspective view of one of the indicating cards carried by the designator body.

Fig. 7 is a perspective view of oneof the guides used for supporting the respective data cards or advertising cards.

For the purpose of illustrating the application of my invention I have shown in Figs. 1 and 3 anordinary timepiece A having? a casing 10.shown in dotted lines in Fig. 3, a face 11, and the usual hour and minute hands 12 and 13. The casing 10 as'illustrated is of rectangular shape, though it will become apparent that the device'may be attached to other forms of timepieces. Y

The invention proper consists of a back 14 formed of sheet metal, cardboard or otherV suitable material which is preferably circular and is provided with a circular opening 15. The back 14 is adapted to be positioned over the face 11 of the timepieceA so that the same andthe hands v12 and 13l of said timepiece are visiblethrough the opening 15 insaid back.

The invention is held supported upon the timeplece A by means of afrectangul'ar frame 16 whichlits around the exterior of the casing 10, and `which is rigidly secured to the hack 14, being properly positioned relative to the opening 15 so that when the device is applied to the timepiece said opening becomes centered with the face of the timepiece. This frame may be constructed vof wood and the kback 14 nailed or screwed to,

it, or'the sameV may be of metal and soldered, welded, or riveted to the back as desired.

As before stated, the opening 15 in the back 14 is centrally located relative to the face 11 of timepiece A with the inner marginal portion 17 in close proximity to the circle on which the numerals and minute graduations of thetimepiece are arranged. In conjunc- Y tion withthis back, I provide a number of detachable designators B which are adapted to be attached tothe marginal portion 17'of back 14 and which have points 18 directed inwardly towards theknumerals minute graduations and hands of the timepiece. These designators may be moved about along the marginal portion 17 and the number of such designators varied at will so as to indicate the occurrence of any number of events Within the limits ofthe device.

In addition to the marginal portion 17 for carrying the designators B I provide' an annular band 19 similarto the back 14, which is positioned behind the back 14 and has an opening 20 in it of'less diameter than the opening 15 and which is concentrically arranged relative thereto so as to form an eX- y 14 Without interference With said band, and

may be attached to the back 14 by riveting, welding, soldering, or any vother suitable means. Uponthis band may be placed other designat'ors C which can be' arrangedin any number or position along the marginal portion 21 thereof, the same as the designators B.

The construction of the designators B and C which is identical', is clearly illustratedin Figsf' and G. Thesedevic'es are formed vofv sheet metal and comprise a body portion 23 rectangular in shape and Vprovided with a point 24. The edges 25 and 2G of said body portion are turned over to forni guides for the reception of a facing 27 shown in detail in Fig. 6, which isof the saine shape as the member 23. 1 From thebody portion 2S is struck out av finger 28 which lies parallelfto said body portion and in spaced ielation'thereto. In placing the designator upon its support, the facing 27 isslid into'th'e guideways 25 and 26 and the entire device slipped over the inar` ginal portion upon Which it is to be mounted, said portion lying between thebody 23 and the ing'e'r 28 as illustrated in detail in Fig. 4. The body 23 and finger 28 are preferably constructed vof spring material so as to cause the designator to yremain. firmly attached With this construction it can readily comprehended that the designatorsmay bemounted along either ofthe portions 17 or 21 in any position around the same, and that any facings 27 may be used in conjunction with them.

"Iogether With the other features of the invention, thel device is 'adapted to carry a number of arcuate display or advertising cards 29 which are arranged circumferential- 1y about the faceof the back 14, and in addition other display cards 30 used lfor giving data connected With the use of the invention or for advertising or other purposes.' These cardsv are Vallheld in place by means of guide bars 31 shoivn in detail in Fig. 7. These bars are preferably formed of sheet metal being bent over to give them an H-sliaped cross section providing flanges 33 and 34 connected together to form oppositely facing grooves 35 and 36. The bars 31 are soldered or other- Wise secured to the front and rear of the back 14 in radial relation so as to receive the respective cards 29 and 30, vas illustrated lin Figs. 1 and 2. The grooves 35 vand 36 are of such dimensions as to cause the cards to become lodged therein by frictional engagement with the anges 33 and 34. In conjuncl tion with the advertising cards 29 I employ a number of radial pointers 38 Which are formed along the inner edge of the back 14 and Which lead from the central portion of each of the cards 29 and are directed towards the hands 12 and 13; These pointers have the psychological effectoffdravving the observers attention to the advertising matter on vthe cards 29, Whejnithe hands l2 and'l and said pointei's come in alignment.

Aii exceedingly practical use to which the` invention may be putis to indicate the arrival or departure of street cars, trains, or busses. When so used both sets of desigiiators B and C are employed, each positioned upon their respective marginal'portion or support v17 or 21. In this case the designators B'a'rejus'ed to indicate the arrival of out'k bound cars and designators C to indicate the arrival of inbound cars. rJ'Dhese designa tors are arranged opposite the exact divi sions of the, hour at Which the cars arrive. As the minute hand 18 moves along, *the observer caii readily ascertain the time heA WillI Although I have explained the invention as used for the purposes of indicating the arrival or departure of trains, busses, street cars and the like, it can be readily understood that the invention may bev used for other purposes. V i

The invention is particularly advantageousl in that the saine can be constructed at an economical cost and can' be easily applied to existing timepieces Without defacing'or reconstructing them. The designators may be 'easily removed or replaced. to conform With'changes inservice andthe various types of service may be easily indicated by 'provid ing the necessary facings.

Having described 'my inventionin the form Which I consider the best embodiment' thereof, I desire to have it understood that the invention may be constructed in diii'er ent Ways and put to uses other than those disclosed Within the scope of the following claims:

1. A schedule indicator comprising a backhaving a circular portion, means cai rying a series of graduations arranged in proximity to` said portion and designating means detachably mounted upon :said por# tO'IL v n 1 Y 2. A schedule indicator comprising a back having a central' opening, and forming a marginal portion, a band positioned :inwardly of saidy opening and forming a second -marginal portion, means carrying a series of graduations arranged in proximity to said marginal portionsand designating Further, by observing the:
